06 Interceptor Question 's

I recently recieved an 06 Interceptor in a trade, and this gun is phenomenal.
I need to know a few things though.
#1. How do I adjust the velocity.
#2. My front block comes loose every now and then.
What can I do to fix this other than loctite?

For velocity, use the adjustment at the bottom of the HPR, assuming it's the stock HPR.
Set your LPR to 100psi, that's the one that is attached to the front block.
You should probably verify/set your board to stock settings, then work your way up from there, or at least make sure your dwell is set to stock. Changeing your dwell can also change velocity. But you should balance your regs first, then go to dwell.

As for your other question, not sure. But make sure you have a screw going into the reciever from the frame. It's right at the top of the trigger guard, next to the trigger. If that comes out it will seem like the front block is loose. Mine came out all the time until I put some blue locktite on it.
